I feel my scrotum, testicle and penis is warm like I have a fever, like a burning sensation.?

Its been going on for a week. I dont understand I googled it and it said Testicular cancer. But I dont have any other symptoms. I also have burning or feverish sensation on my toes and nails but my body temp is 96F. I have mild back and lower back pain and mild cough. Whats wrong with me?
